Lamar Odom -- Back in the Danger Zone

Lamar Odom threw himself back into the lion's den last night ... arriving at LAX, where swarms of photogs are always on the lookout for celebs ... and he NEARLY lost his cool.

Lamar was walking through one of the terminals when he claims a pap nearly ran him over. The photog denies the accusation, but you can tell ... Lamar's pissed.

At one point, Lamar looks the pap in the eye and says, "Don't antagonize me." He then publicly humiliates the guy with the biggest diss of all time ... you gotta see it.

Good thing Lamar kept his temper under control -- for the most part -- as we reported, he agreed to stay on his best behavior after his epic pap confrontation over the summer. He also agreed to get anger managementcounseling.
